Diamond Duke online slot game
Diamond Duke combines a polished presentation with high variance in a simple, mobile-optimised video slot. Reel combinations are only part of the draw: the main goal is to activate both bonus wheels for the chance to win multipliers of up to 100x your bet.
Theme and Storyline
Diamond Duke’s concept is clear as soon as the video slot loads. It takes a classic slot theme and gives it a small twist: rather than filling the whole screen with reels, it shows a first-person view of the entire fruit machine.
Graphics, Sound and Animation
Diamond Duke draws on retro fruit-machine design, but its visual style is crisp and modern. The game features colourful, well-crafted full high definition graphics and is designed for mobile and desktop screens. The audio retains traditional fruit-machine effects.

Top Casinos to Play Diamond Duke:
Gameplay
Diamond Duke features 3 reels and 5 paylines, with the potential for decent payouts through its three bonus features. A winning combination must start on the leftmost reel and show three matching symbols on an active payline towards the right.
The six regular symbols are Cherries, Grapes, Melons, Bells, Sevens and Diamonds. Diamonds offer the top symbol payout at 160x your total stake. Filling every position on the reels with the same symbol pays on every payline and also awards a free spin on the Multiplier Wheel.
Consult the Diamond Duke paytable for returns on each available symbol combination and details of the three bonus features.

Bonuses and Free Spins
Each of the three bonus features starts when ‘Wheel’ scatter symbols land on the reels.
Bonus Wheel: Two ‘Wheel’ scatters anywhere in view award 4x your bet and 1 spin of the Bonus Wheel. Possible results include multipliers of 2x, 3x, 5x, 7x or 10x your total bet, as well as the ‘Pick & Click’ bonus feature.
Multiplier Wheel: Landing 3 ‘Wheel’ scatters anywhere on the reels awards 8x your total bet, plus a free spin on both the Bonus Wheel and the Multiplier Wheel. A result of 2x, 3x, 5x, 7x or 10x on the Multiplier Wheel is added to the Bonus Wheel multiplier. Combined rewards can reach up to 100x your total bet.
Pick & Click: The Bonus Wheel can trigger ‘Pick & Click’, where random multipliers are offered over as many as three stages. Choose ‘Collect’ to end the game or ‘Upgrade’ to continue. Stage 1 offers bet multipliers from 2x to 7x; Stage 2 offers 3x to 15x your bet; Stage 3 can award 5x to 100x your bet.
Bet Sizes, RTP and Variance
Stakes range from 0.05 to 100.00 per spin. The stated RTP is 96.23%, and variance is high; neither figure guarantees frequent or large payouts.
Conclusion
Diamond Duke is a steady classic video slot rather than a game that pays out regularly, though wins can be substantial when they land. Its main draw is activating the bonus features, where the larger multiplier opportunities lie.
